What the heck is part 5? Do you mean the Goron Mines? You have to defeat the mini boss by sumo wrestling him - You learned this technique when you wrestled the Mayor back in the Ordon Village and then again when you wrestled the Goron at the beginning of the mines. Keep your iron boots on and dodge him with the nun-chuck button back and forth then grab him low- you can strike him by rolling into him with your iron boots but you must toss him off the floating mat three times to defeat him - The holy trinity of Zelda is THREE - always 3. Once you defeat this mini boss you will be given the bow and arrows. Probably one of the most valuable weapons in the game since you will use it throughout the rest of the game -
